TheWow64parametersimulatesa32‐bitenvironmentfor32‐bitapplicationsthatcannotrunona64‐bit
Windowsoperatingsystem.

QualityReportingEnabled
TheQualityReportingEnabledparameterspecifieswhetherVMwarecancollectanonymousdataona
packagetoimproveThinAppapplicationsupport.VMwarecollectsapplicationinformationsuchasthe
versionandnumberofapplicationfailures.
Ifyouagreetoanonymousdatacollectionduringthecaptureprocess,theQualityReportingEnabled
parameteruploadsdataeverytendays.

Configuring Isolation
Youcan modifyThinAppparameterstodeterminethereadandwriteaccesstothefilesystemandregistrykeys.
DirectoryIsolationMode
TheDirectoryIsolationModeparameterspecifiesthelevelofreadandwriteaccessfordirectoriestothe
physicalfilesystem.
ThecaptureprocesssetstheinitialvalueoftheDirectoryIsolationModeparameterinthePackage.inifile.
Thisparametercontrolsthedefaultisolationmodeforthefilescreatedbythevirtualapplicationexceptwhen
you
specifyadifferentisolationmodeinthe##Attributes.inifileforanindividualdirectory.
Any unspecifieddirectories,suchasC:\myfolder,inherittheisolationmodefromthePackage.inifile.
ThinAppprovidesonlytheMergedandWriteCopyisolationmodeoptionsinthecaptureprocess.Youcanuse
theFullisolationmodeoutsidethewizard
tosecurethevirtualenvironment.
WithMergedisolationmode,applicationscanreadandmodifyelementsonthephysicalfilesystemoutside

appearonthephysicalsystem
inthelocationthatusersexpect,insteadofinthesandbox.Thedisadvantageisthatthismodemightclutter
thesystemimage.Anexampleofthecluttermightbefirst‐executionmarkersbysharewareapplications

WithWriteCopyisolationmode,ThinAppcaninterceptwriteoperationsandredirectthemtothesandbox.
YoucanuseWriteCopyisolationmodeforlegacyoruntrustedapplications.Althoughthismodemightmake
itdifficulttofinduserdatafilesthatresideinthesandboxinsteadofthephysicalsystem,thismodeis
useful
forlockeddowndesktopswhereyouwanttopreventusersfromaffectingthelocalfilesystem.
